Start off with your fabric. I used knit fabric for the turquoise one but I made some out of regular cotton and they came out great too. Trace a circle onto your desired fabric.
Dot center of circle with glue. Fold outer edge of circle half way in, and glue onto center of circle.
Put another dot of glue in center (over the part you just folded). Take the "open" side that you just folded and bring to center on top of glue dot.
It should look like this.
Until you get something that looks like this. You should end up with a total of 5 folds (depending on your size of fabric).
Snap it onto a hair clip and you're done!
